The angle AOB has a measure of 72 degrees

The formation of angles is as a result of the intersection of multiple lines intersect.

The given parameters are:

The above means that

AOB = BOC

So, we have

6x - 12 = 3x + 30

Evaluate the like terms

3x = 42

Divide by 3

x = 14

Substitute x = 14 in AOB= 6x -12°

So, we have

AOB= 6 x 14  -12°

Evaluate

AOB= 72°

Hence, the measure of the angle is 72 degrees

The given equation x² + 6x - 5 can be written in the form of (x + a)² + b as

 (x + 3)² - 14.

In math, we can state that the process of "completing the square" is taking a quadratic equation of the form ax² + bx + c = 0 and changing it to write it in the form a(x + p)² + q = 0. Find the roots of a quadratic equation often using this method.

Given quadratic equation is x² + 6x - 5.

To convert it in the form (x + a)² + b, where a and b are numbers.

x² + 6x - 5

x² + 2 × 3x + 3² - 3² - 5 (convert the equation into a perfect square)

(x + 3)² - 9 - 5

(x + 3)² - 14

Hence, the required equation is (x + 3)² - 14.

Calculating a value using operands and a math operator is referred to as performing a mathematical "operation." The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.

A set of numbers and operations make up a mathematical expression. The components of a mathematical expression that performs an operation are:

Operands: Operands are the numerical values that are employed in an operation. Different words are given to the operands depending on the type of operation.

Operator: An operator is the symbol used to represent a mathematical operation.

Solving the above;

Membership costs him= $50

Per game rented= $3

Amount he spent = $296

Therefore, Number of games he rented=[tex]\frac{296-50}{3}[/tex]

Camila filled up a 4-gallon bucket in just 1/6 of a minute

Here we have to use the unitary method to find the rate of water flow through the hose

The quantity of water filled in 1/6 of a minute= 4 gallon

The quantity water filled in one minutes = The quantity of water filled in 1/6 of a minute ÷ (1/6)

Substitute the values in the equation

6 2/3 liters of water should be mixed with 10 juiced lemons to obtain the same result as Four liters of water are mixed with 6 juices lemons to make lemonade.

A single or distinct unit is referred to by the word unitary. Therefore, the goal of this method is to establish values in relation to a single unit. The unitary method, for instance, can be used to calculate how many kilometers a car will travel on one litre of gas if it travels 44 km on two litres of fuel.

A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4).

By using unitary method, 4 liters was water has 6 lemons

1 lemon will have 4/6 liter of water.

So 10 lemon will have

(4/6)*10=40/6

Answer:

Step-by-step explanation:

The value of the given function [tex]log_6x+log_6(x-1)=1[/tex] is x = 3 or x =-2

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In the simplest case, the logarithm counts the number of occurrences of the same factor in repeated multiplication; e.g. since 1000 = 10 × 10 × 10 = 10^3, the "logarithm base 10" of 1000 is 3, or [tex]log_1_01000=3[/tex].

We know that

Log (a) + log (b) = log (ab)

So, [tex]log_6x+log_6(x-1)=1[/tex]

[tex]log_6(x(x-1))=1\\log_6(x^2-x)=1\\x^2-x=6^1\\x^2-x-6=0\\[/tex]

(x-3)(x+2)=0

So, x = 3 or x = -2

The equation of the line that passes through the point (8, 5) and perpendicular to y = −12x +7 is y = (1/12)x + 13/3.

We know that,

The product of the slopes of two perpendicular lines is -1.

The slope intercept form of a line is given by :-

y = mx + c

Comparing it with y = -12x + 7

We get,

m = -12 (slope of the line)

c = 7 (y-intercept of the line)

Let the slope of the line perpendicular to the given line be n.

Hence, we can write,

(-12)*n = -1

n = 1/12

Also, the line passes through (8,5).

Hence, we can write,

5 = (1/12)(8) + c

5 = 2/3 + c

c = 5 - 2/3 = 13/3

The interval that describes where the graph of this function is negative is: C. 2 < x < ∞

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

Generally speaking, a function is typically used for mapping an input variable to an output variable. In Mathematics, the value of y on the y-axis of a graph must be less than 0 (x < 0) for the graph of any function to be negative.

By critically observing the graph of this function, we can logically deduce that at point x = 2 is where the value of y becomes less than 0 (x < 0) and continues to infinity. Therefore, the graph of this function is negative is at an interval of 2 < x < ∞.
